Comments about Educational Insights MathShark®:

My 8yo twins received this for review and were actually excited to practice math with it during their summer vacation! It requires 2 AA batteries in a rear compartment that can be unscrewed with a coin. As stated in other reviews, the battery door bulges with the batteries inside although it does not affect the function. The screen is a very basic design typical of a calculator but with functions that allow testing in addition, subtraction, multiplication, division, decimals, fractions and percentiles. There are 9 levels for each function and a help button to provide clues. It's simple enough that my 6yo was able to figure it out and the green and red light next to the screen lets the player know if they have the correct answer. Its an easy to travel with ergonomic shape great for travel but the screen is not so clear in dim lighting (in the car). It's great for building math skills and since my kids are happy to play with it as an electronic toy I'm very happy.

I received the Math Shark game and calculator for my second grader. Subjects covered are addition, subtraction, multiplication, division, decimals, fractions, and percentages. A guide/instruction book is also included. Two AA batteries required aren't included.

For game mode, you choose the topic, level of difficulty, and the sound on or off. The screen displays examples before the game begins. If the answer is correct, it lights up green and makes positive sounds. If it's wrong, it lights up red, makes negative sounds, and shows you the correct answer. At the end of the game, it tells you the elapsed time. Problems answered incorrectly are reused in the game.

There are a couple of nice features. Math Shark will go into sleep mode after 300 seconds to conserve battery life. There's also a help button to give hints if you are struggling.

The guide is helpful and well-written. For each subject, it describes the content tested at every level and gives sample problems and tips. It also contains an assessment chart which you can use to keep track of your children's progress.

There were a few things that I didn't like. The screen can be hard to read, depending upon the light. Another thing I noticed is that in calculator mode, it doesn't appear that you can use the percent or fraction functions. Numbers must be converted to decimals in order to use the calculator. Also, this device can only be used for math, unlike a computer or tablet. On the flip side, since it can only be used for math, your children won't have the distractions from a computer or tablet.

I like the concept of this product. Children can do this independently and parents no longer have to hound their children with flash cards. Since various subjects and levels are offered, it's useful to kids of multiple ages. This can be used while traveling or at an appointment or restaurant with the sound muted. Educational Insights sent me this product in exchange for an honest review.

My 6 year old son loves numbers & this is perfect for him. The device was easy to hold and is small enough that we brought it on the airplane during vacation. My son was able to play the game independently and enjoyed the green/red lights to indicate correct/incorrect.

This toy is a hit with my 6 year old son! My son loves math, so when we received this product, he immediatly wanted to start playing with it. I like that you can add, subtract, multiply, and divide with it, so my son will be able to grow with this toy. He is going into 1st grade, so it is nice that he can practice adding and subtracting, all while having fun with 'an electronic' toy. He even took it with him in the car and played on it the entire 4 hour car ride to go on vacation.The screen it a little hard to read if the light hits it just right, but it is easy to hold and my son will be able to grow with it.

My daughter was thrilled when she got this to use. She is always trying to learn math above her 7-year-old level and this is great for that because it allows you to adjust the difficulty. Love how it has sets for addition, subtraction, multiplication, and division and even tougher problems like fractions. She was able to quickly figure out how to use it herself. My one complaint is the screen is a bit difficult to read if you aren't in the right lighting. But otherwise, I'm excited to have her use this as she goes further in school to practice tougher problems. It's also a great size for the car or waiting for an appointment. I received this product free from Educational Insights in exchange for an honest review.

My four year old loves math and electronic gadgets and Math Shark was a hit with him! He currently likes doing the easier levels of addition and subtraction and I like that this product will grow with him as his math skills develop further. It is convenient and educational - wonderful for travel or just small outings where waiting is necessary (like going out to eat). My six year old plays with the Math Shark occasionally and although she's less a fan of the product (because it is dedicated only to math) that is also another plus for the parent - you know your child won't be switching over to some mindless ice cream game instead of practicing math if you have the Math Shark vs. a tablet. Also, this product makes it so much more fun to do math drills than having to use flash cards. I would give this product five stars if the display screen was clearer - the numbers are sometimes hard to see/distinguish. Overall, this is a product I would recommend.*I was provided the product in exchange for an honest review*

My daughter was excited to practice math with this learning tool. The shape is nice, making it easy to hold, and everything seems very sturdy. I like how you can choose the learning level so this device can grow as my kids progress in math. The sound and light-up feature for correct/incorrect answers make this an easy-to-use learning tool.

Educational Insights Math Shark has been a big hit in our home! My 7 year-old son has really enjoyed playing with it and finds it easy to understand. Math Shark has several games to choose from including addition, subtraction, multiplication, division, decimals, fractions, and percents. Each game also has various skill levels. There is even a calculator mode! Math Shark is portable and would be a great toy for car trips. It kept my son entertained for quite some time.

My daughter is in 2nd grade and this product works well for drilling basic math facts. I like that you can select different levels of difficulty and different operations to practice. I also appreciate that this is a product that will grow with my child, and she will be able to use to drill the basics for several years. And of course, these drill can be done on computers or tablets or phones, but those things have all sorts of other distractions on them; if she's working on this, at least I know it's math she's practicing!

The kids were excited to receive this and played with it for awhile and then lost interest. I tried to get them re-interested but no go. I'm hoping now that summer is over I may be able to re-introduce it and have positive results like when it first arrived.
